To all whom it may concern:

Be it known that I, WI LIAM A. LORENZ, a citizen of the United States,and resident of Hartford, in the county of Hartford and for-Molding PulpState of Connecticut, have invented certain new and useful Im rovementsin Apparatus ticles, of which the following is a full, clear, and exactspecificationl My invention relates to a pulp molding machine, and theobject thereof is to produce ana paratus which will manufacture pulparticescomposed of layers of pulp of differ-- 'one of these cooperatingmold-faces foreach of the mold-faces carried by the carrier, the movablemold-face being adapted to travel in the two outer vats, and later on tocooperate or nest with the carrier mold-faces, and to discharge thearticles, the whole apparatus being connected with suitable drivingmech-' anism, and a conveyer for taking off the articles as they areformed. In this machine the articles are molded in layers from twogrades of pulp, and these layers are then combined. The shape of themold depends upon the shapeof the article. In order to make pulp vesselssuch as butter dishes, one mold-face is made concave or depressed, andthe other mold-face is made convex or raised. One of the sets ofmold-faces is carried upona traveling or rotating carrier and the otherof the sets of cooperating-mold-faces is carried by movable oroscillating arms, connected to the carrier. One of the sets ofmold-faces during their travel or rotation in one vat, which may be thedepressed mold-faces, will have deposited thereon, one of the grades ofpulp contained in its particular vat. The other set of mold-faces, whichmay be the raised moldfaces, are moved or rotated in two othervats,adjacent to the first vat containing another grade of pulp, and, whiletraveling in these vats, the desired amount of pulp will be depositedupon those mold-faces. Then at a point farther on in the travel ofthecooperatmg pairs of mold-faces they are brought together while wet, andthe layer upon one mold-face is deposited or nested in the other layer,supported by the other mold-face. The two layers are thus combined, andif desired they may be compressed between the two mold-faces. Thenthecooperating moldfaces are separated, and a blast of air is employed,operating through one of the moldfaces, to detach the vessel from thatface, and transfer it to the other face. Thelatter then moves awaysufiiciently to enable the completed vessel to be discharged therefrom,which is done preferably bymeans of a blast of air operating through themovable moldface, thus detaching it therefrom, The vessel may bereceived by meansof a suction take ofi, or by any other suitable means.

The apparatus may be utilized as a machine for making two-layer pulparticles, upon one side 'of, the carrier, or upon both sides of thecarrier. 7 In the latter instance the devices utilized to'bring thetwooppositely disposed pairs of mold-faces together.

to combine the pulp layers will exert a pressure towards one another,and thus prevent a side thrust u on the rotating carrier. When makingtwoayer pulp vessels in the oppositely disposed series of mold-faces,the central ones carried by the carrier travel or rotate in a centralvat containing one grade of pulp, and the two outer series of mold-facestravel or rotate in two outer pulp vats, each one of which contains adifferent grade of pulp, thus producing two series of vessels at thesame time. A cheap grade of pulp may be employed for that layer of thepulp vessel which does not need to have a fine appearance, and thislayer may be the greater amount of pulp necessary in a complete ves fromthe a paratus by suitable means, and

then trans erred to compressing devices detached from the machine. V

Fig.- 13 shows a sectional.view of the mold carrier and the cooperating movable mold Icarrier withtwo cooperating mold-faces instead of one.

.In the drawings three vats are shown, an inner vat 16' and two outervats 17 and 18, the inner vat containing one grade of pulp,

- and the outer vats containing another grade of ulp. These vats areprovided with suitable bafile plates 19, and inlet 20, for supplyingpulp. Pulp is'supplied to these vats by suitable apparatus not shown.

In the two u rights or main brackets 22 and 23, is place a hollow fixedshaft 24, u on which rotates the mold carrier 25. he mold carrier 25 isprovided with hubs 26, to one of which is secured a gear 27, whichmeshes in a pinion 28, upon a shaft 29, which is driven by suitablemeans, not s own.

. The fixed shaft 24 is provided with a hollow portion 32 connected by api e 33 with suitable exhaust mechanism, not s own. The other end of theshaft 24 is rovided with a hollow portion 34 connecte [with a pipe 39 tosuitable air pressure apparatus not shown. The hollow ortions 32 and 34are separated by means 0 a partition 35.

The exhausting apparatus and air pressure apparatus are similar to.those shown in the patent to Geo. R Ward, No. 828,909 dated Aug. 21,1906, and need not be particularly described, except that they operatein sub-. stantially the same manner, in order to provide suction andair' pressure at suitable times. The hollow portion 32 connects throughan disposed mold-faces carrie The shaft 24 is provided with a blastaperture 40, which at the pro er timemay communicate with the passageway37 and chamber 38, in order to exert air pressure therein,

also provided with two exhaust apertures '41 connecting with passagewaystothe movable mold-faces carried by the carrier which will be describedlater on, anda'lso with two blast apertures 42.

The carrier 25 is provided with two side faces, a right face 44 and a'left face 45. Into these faces are inserted detachable molds 46 and 47,situated in the right and left faces respectively, and fastened to thecarrier by means of suitable screws 48 which locate the molds thereon.These molds are shown in may hang to the smooth faces of the carrier. I

The carrier 25 may be provided in one or both of its faceswith as manymold-faces as desired, six being shown upon each side, in the drawings.The more mold-faces there are, thelonger will they stay in the pulpvats, and the more pulp can they thus accumulate.

Upon-the hubs 26 'of the carrier 25 are secured a series of brackets 52.brackets are ivoted movable or oscillating arms 53,hel(i in the bracketsby means of through bolts 54. These armsc'arry detachable mold-faces 55,being attached to the arms by screws 56 which locate the molds on thearms. These mold-faces are provided with drainage openings 57. Theraised portions of these mold-faces are provided with suitable wirenetting and'wire auze. The contour of these raised moldaces depends uponthe thickness of the vessel formed between the raised and the depressedmold-faces, and the raised one will be the smaller.

The movable arms 53 are provided with chambers 58 below the raisedmold-faces. These chambers communicate with" apertures 59, the latterleading to apertures 60 in 1 5 the bolts 54, and then communicating withapertures 61 in the lower portion. of the arms,

e latter communicating withthe apertures 41 and 42 in the fixed shaft24-, in or er to be in communication withthe exhaust orthe 120 example,upon posts 65. The oscillating 125 arms 53 may be provided with rollers66, running against the track 64. After the firms have been pushedinwardly by means a I cf the tracks, they may be drawn outwardl by meansof springs 67 attached to the hu 130 In these 26 pr to any suitabledevice carried thereby. The arms 53 therefore, receive a motion whichseparates them from the central mold carrier, and allows the moldscarried by the arms to dip'into the two outer pulp vats 17 and 18; afteremerging from those vats they then move-inwardly until the mold-faces 55approach the mold-faces 46 and 47.

V A deposited upon both mold-faces, these two Each oscillating arm 53 isprovided with a valve 69. It is furnished with an opening 70, whichconnects the upper and lower ortions of the passageway 59, and whic ifturned, connects the upper part of passageway 59 to the outeratmosphere, through the opening 71.

The valve 69 is provided with a lower arm 72, which is closed during thetravel of the carrier by a dog 73 attached to the track 64. The valve isalso provided with an upper arm 74, which during the travel of thecarrier strikes a dog 75 attached to the track. By referring to Fig. 12,it will be seen that the arm 72 moves from the dotted position 76 to thefull line position of the arm 72, to move the valve from the exhaustconnection shown inFig. 9, to the position shown in Fig. 10, in whichthe valve is open to the atmosphere. The upper arm 74, after strikingthe fixed dog 75, moves to the dotted position 77, shown in Fig. 12.This closes the valve to the atmosphere and connects the upper and lowerportions of the passageway 59.

After the desired layers of pulp have been layers are combined bybringing the moldfaces together. Then the combined vessel is transferredby atmospheric pressure upon the raised mold-face, which is then movedoutwardly to the position shown in Fig. 4.

In this position the completed pulpvessels may be taken or blown fromthe cooperating mold-faces and delivered to suitable take-off apparatus.These may be of the neumatic type, which by means of suction tthedetached vessel from the movable mold-faces and deliver them totraveling belts or conveyers. These take-ofi devices form no part of thepresent invention, and will therefore only be referred to briefly. Thepneumatic suction device consists of a suction hood 80 connected to arising and falling arm 81, which receives that motion from a fixed Thearm81 is connected to a rotating spider 83, driven by the shaft 84,bevel gear 85, and bevel pinion 86 secured upon or driven by the hubs 26of the moldcarrier. The shaft 84 revolvesin abracket 87 fixed to themain frame of the machine. Suitable suction devices andblowing ofidevices, not shown, control the and discharging of the pulp'vessel toand from the hood 80, disthe vessels upon a traveling belt 88.

time the oscillatin Fig. 13 I have shown in section mulof a largemold-face, two -or more mol-dfaces of a smaller size may be introducedinto the machine in the same position occupied by the l'ar ermold-faces, and are thus interchangeab e. In this manner a larger outputmay be procured from the machine when making small size pulp vessels. 7

The operation of this machine is as follows :The mold carrier 25 turnsupon the fixed shaft 24, dipping the carrier molds 46 and 47 insuccession into the vat 16. During this dipping operation, the exhaustor pumping apparatus exhausts the air from the interior 32 of the shaft24, a erture 36 and from the passageway 37 and c amber 38. During thisoperation a layer of pulp 93 is deposited upon the depressed faces ofthe two molds 46 and 47, the thickness emerge from the vat, the faces 44and 45- of the carrier are scraped ofi b the scrapers 50, leaving thelayers of only in the depressed faces of the mol At the same arms 53,carrying the cooperating moldaces 55, are swung to the outward positionshown in the lower part ofFig. 2. During the rotation of the carrierthese mold-faces 55 dip in succession into the pulp vats 17 and 18, oneseries of mold-faces 55 dip ing into the vat 17, and the other series ofside, dipping into the vat 18.. As the arms 53 move around, afteremerging from. the vats 1 7 and 18', they are swung inwardly towards thedepressed mold-faces. 46 and 47 mold-faces on the other by means of thetrack 64. During this operation the valve 69 in each arm is successivelyset so as to communicate through passage 70, i with the upper andlowerportions of the passageway 59. During the dipping o eration. and for aportion of the time t ereafter, until just efore arriving at theposition C in Fig. 3, the exhausting apparatus exhausts the air throughthe opemng 32 of the shaft 24, and through the o enings .41, passageways61,

60, 59, and c ambers- -58 and causes the layers of pulp 94 to bedeposited uponthe raised faces of themold-faces 55. During the continuedmotion ,of these mold-faces frdmthe vat up to. the position C in Fig. 3,C,

the exhaustingapparatus drains water through. the arms 53. The thicknessof the (I in Fig. 3 is represented in sectional view by Fig. 9, at aboutposition B in Fig. 3, and the arrows below both of the moldfaces in Fig.9 show the direction of the air pressure duringthe exhausting operationfVlfhen moving from C in Fig. 3, the mo each other, as shown in Fig. 10..During this latter motion,.the valve arm 72 moves from position 76 tothe position shown in Figs: 3 and 12, having been moved by the dog73attached to the track 64. In this position B to position position thevalve 69 is open to the atmosphere through the aperture 70, 71-. Whenthe mold-faces have been brought together as shown inthe upper portionof Fig. 2, the pulp layers carried by the mold-faces 55 are nested inthepulp layers carried by the mold-faces 46 and 47, and are then combined.The tracks 64 are so positioned that the rollers 66 durin the rotationof the carrier move the osci lating arms 53, carrying the mold-faces 55inwardly, exerting the desired amount of pressure upon the double pulplayers between the two cooperating pairs of mold-faces. As thesemold-faces are oppositely disposed between the tracks, no side pressureis exerted against the central mold carrier 25'.

In Figs. 5 and 6 connection between the chambers 38 and the-hollow part32 of the shaft 24 is shown. In Fig. 7 the chamber 38 andpassageway 37is shown cut off from the opening 36, which ends the connection with theexhaust apparatus, as shown in the upper portion of the machine in Fig.2 and that position 0 in Fig. 3. The parts then'move from-the Ipositionshown in Fig. 7 .to that sageway 37 into the chamber 38, and through theperforated depressed mold-faces shown in 1g. 8. This connects the airpressure passage 34 with the aperture 40, permittmg air pressure to passthrough the pas- 46 and'47. The movable mold-faces then move fromposition 0 to position D, Fig. 3, and in doing so they are movedoutwardly in succession to the position shown in Fig. 11, being drawnthere by means of th'e'springs 67. -As the cooperating raised mold-faces55 leave the depressed mold-faces 46, the air ressure in the chamber 38forces the comined pulp vessels awayfrom the depressed mold-faces, andholds them upon the movable mold-faces 53 during their outward motion;the air pressure at the start passing through the pulp vessels entersthe chem-- d-faces move towardssnare bers 58, and through thepassageways .59,

and through the valve. openings 71 to the outer atmosphere. The movablemold-faces 55 then move from position D in Fig. 11

and Fig. 3, ,to the outward positions shown in Fig. 4. During this timethe arm 74 of the valve 69 is turned from position 74 to 77 shown inFig. 12. This turning of the valve establishes a connection through thevalvewith the upper and lower portions of the passageway 59 and closesthat valve to the outer atmosphere. The outer positionspf the two arms53 shown in Fig. ,4 is at E in Fig. 3. In this .positionthe air pressurein the hollow part 34, passes through the openings'42, and through thevarious passages into the chambers 58. This air pressure'is exertedthrough the openings in the moldsion and delivers them to any suitabletakefaces 55', and detaches the combined pulp vessels from the'raisedmold-faces in succes-' 5 off means, which in the present instancecomprise the suction hoods 80. These, by means of pneumatic pressuretake the completedvessels and carry them around to, and drop them uponthe conveying belts 88. The arms 53 then move successively toward thecarrier mold-faces a little, in order to pass around and into the twovats 17 and 18, afterwhich the operation of producing these pulp vesselsis repeated upon each of the pairs 'of coeperating moldsin succession.-

This machine may be utilized as a single machine, making a series ofduplex or twolayer vessels upon one side only of the car' rier 25. Or ifpreferred,- the vessels may be carrier. The machine may also produce onesize of pulp vessel uponone side of the mamade at the same time uponboth sides of the out departing from the spirit of the inven- I tion.For example, the movable arms carried by the rotating carrier whichsupport.

the cooperating mold-faces may be made slidable upon that carrier,instead of having an' oscillating movement, so long as the parts performthe functions" described. These movable arms may also be controlled byclosed cams, thus dispensing with the return springs.

The mold-faces in the specification have been termed depressed andraised" mold-forms; these terms are used for convenience. If the formof. the article demands other may be fiat, or also swarm it, one.mold-form may be de ressed, .and the epressed, when making disks, forexample. Either form may be carried on the carrier or the carrier arms,provided the mold-faces during their traveling movement receive separatelayers of pulp and then cooperate to combine the layers into a vessel orarticle having more than one layer.

As a machine for making separate layers of pulp upon coo cratingmold-faces, and then combining t em to. form a multiple layer article isnovel in the art, I desire to broadly cover these devices when carriedby traveling carriers,no matter in what particular manner they travel orreceive the separate layers of pulp, as long as they cooperate tocombine the layers in one completed article.
